Comparative Analysis of China Instrument Industry and International

China's automation control systems and on-site instrumentation and key precision test instruments are still 10 to 15 years apart from the international level.

Gap One: Poor Product Reliability The overall characteristics of modern industrial instrumentation are high reliability, high performance, and high applicability. The gap between most products of Chinese companies and foreign products is also in this respect. For example, China's self-developed decentralized control system (DCS) and electromagnetic flowmeter, the basic performance and functionality of these products has been close to the international level, but there are still some gaps in reliability and engineering application capabilities.

Gap two: Digitalization, intelligence, and low level of integration The technical characteristics and trends of modern industrial instrumentation are digital, intelligent, networked, and integrated, while China's products are generally conventional varieties, and smart products have just begun. Taking nuclear power control systems and instrumentation integration as an example, the gap is even greater after entering the digital control technology era due to the weak foundation.

Gap three: High-tech differential The foreign smart actuators have adopted new technologies such as variable frequency speed control, new-type motors, low-work consumption, micro-piezoelectric ceramic I/P converters, Bluetooth communication technology, intelligentization, and field bus. Start getting started.

Gaps 4: Product precision is low In mass flow meters, for example, the accuracy of foreign measurements is divided into 4 grades, the highest accuracy and can measure the gas is 0.1, the most common is 0.15, while the domestic can only reach economical Grade 0.2 and applicable Grade 0.5. Another example is China's metering at gas stations. . Accuracy of 5%, but the accuracy of foreign 300,000 tons of oil tankers to China's delivery to 0.1%.
